Hi!

I am having trouble keeping the metal moulding trim that is above the windshield, in place. I connect it to the piece over the driver'* door (in the groove) and then I push the rubber down into the groove between the glass and the roof, working my way around to the passenger side. Just when I think I have it, the thing pops out of the groove. Any suggestions on how to keep this in place?

Thanks,
John

did you have your windshield replaced?

My wife had it replaced, probably a couple of years ago now. Do you think it'* something they did/didn't do?

Thanks,
John

when the windshield was put in my 95 before i bought it, it was installed incorrectly, causing the top trim piece to stick out further than it should have, causing water to be able to sit where it wasnt...

i would have the windshield company look at it if they are still around

while on this topic....mine seems to come off at the top all the time...is there a certain glue to use?...if not any suggestions on what type to use to keep it down?

That'* exactly what mine does. I will check with the glass company, but more than likely too much time has passed. If that'* the case, I will either have to figure a way to do it myself, or have the glass company fix it.

Thanks,
John

as far as i know.. the windshield has to be reset...

Add me to the list of people with this problem!! My windshield hasn't been replaced anytime recently, if at all. Would something like weatherstrip adhesive work to hold it down? Any other ideas?

Maybe I can help. My 95 had this when I bought it last summer. All you have to do is put some of the black silicone adhesive trim/body/molding stuff in the groove, press down on the trim, and tape it down while it cures.

Moving to 92-99 (this isn't a detailing topic, it'* more of a mechanical thing).

There are three (3) GM Service Bulletins regarding the adhesives used to retain our windshields; they are as follows:

Windows/Glass - Urethane Adhesive Usage

Bulletin No.: 02-08-48-001A

Date: December 19, 2003

Supercede:

This bulletin is being revised to update the models years, the title and the information contained in the bulletin. Please discard Corporate Bulletin Number 02-08-48-001 (Section 08 - Body and Accessories).

Effective with the sale of existing stock, General Motors will no longer offer the URETHANE ADHESIVE KIT P/N 12346392 (which includes all associated primers). Until this stock is depleted, the GM kit is still recommended. In Canada, the GM Urethane Adhesive Kit, P/N 10952983, which includes all associated primers, will continue to be recommended and available.

As an alternative to the GM Kit for bonded glass installation AND some exterior body panels on specific GM vehicles, various aftermarket materials are recognized as meeting the equivalent of the GM performance specification. This specification (GM 3651G, recently updated) outlines material performance requirements and tests for adhesive manufacturers who develop and manufacture Stationary Glass Urethane adhesives.

Those products currently recognized as meeting those equivalencies are as follows:

^ Dow Automotive (Essex) 400HV (one part and requires associated primers)

^ Dow Automotive (Essex) U216 (two part and requires associated primers) Call Dow Automotive at 1-800-453-3779 for more information.

^ 3M(TM) "Fast Cure" Auto Glass Urethane (one part and requires associated primers) Call 3M(TM) at 1-877-666-2277 for more information.


Any use of these materials should be done as a system by the specific manufacturer. DO NOT intermix primers or adhesives from one manufacturer to another.

New Windshield/Glass Urethane Adhesive Caulking Kit

File In Section: 10 - Body

Bulletin No.: 83-15-16

Date: October, 1998

INFORMATION

Subject:
New Windshield and Stationary Glass Urethane Adhesive Caulking Kit

Models:
1990-99 All Passenger Cars and Trucks

As a result of a change from standard viscosity urethane to high-viscosity urethane, a new Urethane Adhesive Caulking Kit, P/N 12346392, is now available from GMSPO. This kit contains the "High Viscosity" Urethane Adhesive for thicker and more consistent bead size applications. When applied properly, this new high viscosity urethane in many instances will eliminate the need for depth setting blocks or the damming material to control squeeze out.

Like the standard viscosity urethane contained in kit (P/N 12346284) that it replaces, it is a one-part, moisture cure product with curing times that vary as a result of changes in either temperature or humidity.

THE REQUIRED TIME FOR THIS NEW ONE-PART MATERIAL to ensure a safe installation of stationary glass before returning the vehicle to the customer, IS A MINIMUM OF SIX (6) HOURS AT 70°F (21°C) AND 30% RELATIVE HUMIDITY.

Alternate equivalent materials for this kit may be available from a local glass repair shop.

Other manufacturers of Urethane Adhesive that have documented their ability to meet or exceed General Motors specification # 3651M (Performance Requirements for Stationary Glass Bonding Adhesive System Service) are also considered to be equivalent to GM Kit (P/N 12346392).

In previously published Corporate Bulletin Number 73-10-54, increasing customer demands for faster service have resulted in quicker two-part urethane adhesives to be made available. Essex Beta Seal U216* (two-part urethane adhesive) also meets the General Motors 3651M Specification and can be used when the customer demands quicker repair of the vehicle than the above described one-part product can provide.

This two-part, chemical cure product requires ONE (1) TO ONE-AND-ONE-HALF (1-1/2) HOURS FOR CURING BEFORE RETURNING THE VEHICLE TO THE CUSTOMER. This two-part product also requires primers on the glass and pinchweld surfaces. The primers and applicator daubers are not included with this two-part product and therefore, must be purchased separately. In addition, this two-part product requires a special applicator (gun) for proper mixing and dispensing of the adhesive.

Important: The U216 product is NOT available from GMSPO and must be obtained locally.

* We believe this source and their products to be reliable. There may be additional manufacturers of such products. General Motors does not endorse, indicate any preference for or assume any responsibility for the products from this firm or for any such products which may be available from other sources.

When using either of the above described products, make sure to follow the manufacturer'* directions for application and drying times. For information regarding the removal and installation of stationary glass, consult the appropriate Service Manual.

Windshield - Two-Part Urethane Adhesive For Installation

File In Section: 10 - Body

Bulletin No.: 73-10-54

Date: May, 1997

INFORMATION

Subject:
Two-Part Urethane Adhesive For Windshield Installations

Models:
1997 And Prior Passenger Cars and Trucks
(Using Urethane Adhesive To Retain Windshields)

General Motors passenger cars and trucks use urethane adhesive as a means to retain the windshield in the body opening. The urethane adhesive is used to bond the windshield in the opening, increasing vehicle structure.

The current recommended urethane adhesive, GM P/N 12346284, is a one-part moisture cure product that requires a minimum curing period of 6 hours at room temperature before returning the vehicle to the customer.

Increasing customer demands for faster service in recent years have resulted in quicker cure two-part urethane adhesives.

Essex Beta Seal U216* (two-part urethane adhesive) meets the General Motors 3651M Specification (Performance Requirements for Stationary Glass Bonding Adhesive System Service) and can be used when the customer demands quicker repair of the vehicle than the current one-part materials can provide.

Either of these products can be used when glass replacement is performed. The differences between these products are as follows:

The CURRENT URETHANE ADHESIVE KIT, GM P/N 12346284, IS A ONE-PART ADHESIVE. It includes the necessary glass and pinchweld primers and is specified in Service Manuals for General Motors' vehicles. Since this is a "moisture cure" product, the curing time for this one-part material will vary with changes to either temperature or humidity. The REQUIRED TIME FOR THIS ONE-PART

MATERIAL to ensure a safe installation of stationary glass before returning the vehicle to the customer IS A MINIMUM OF SIX (6) HOURS AT 70°F (21°C) AND 30% RELATIVE HUMIDITY.

ESSEX BETA SEAL U216 IS A TWO-PART ADHESIVE MATERIAL THAT PROVIDES FOR A ONE (1) TO ONE AND ONE HALF (11/2) HOUR CURE BEFORE RETURNING THE VEHICLE TO THE CUSTOMER. This product also requires primers on the glass and pinchweld surfaces. This product requires a special applicator for the mixing and dispensing of the adhesive.

When using this (or any) product, make sure to follow the manufacturer'* directions for application and drying times.
